sample holder for selective thermoanalytische studies

摘要

A sample holder for selective thermoanalytical analysis of specimens, comprises a receptacle for the specimen and cover means for the receptacle. The cover means provides a labyrinthine path for escape of gases from the sample. This labyrinthine path can be provided by concentric cylindrical elements which permit the gas to escape past alternately opposite edges thereof, or a helical groove in the outer cylindrical periphery of the cover means that defines the labyrinthine path. A thermocouple for continuously detecting the temperature of the sample is disposed in a central recess in the bottom of the vessel.
